O.S. Engine 160FX Overview and Flight Role
RC airplane pilots who need strong low-end torque and a compact installation will appreciate the O.S. Engine 160FX. As the largest unit in the FX range, it balances robust output with a tight footprint, and its wide, wing-shaped exhaust port helps the engine produce high torque at lower RPMs for smooth aerobatics and steady sport flying.
Installation Options and Practical Design
The O.S. Engine 160FX includes a remote needle valve that supports three mounting styles: vertical, horizontal, or mounted remotely from the engine body. That flexibility makes it straightforward to fit into varied cowl designs and tight compartments, while the engine's fuel efficiency helps extend airborne time between refuels.
Power Band and Component Compatibility
With a displacement of 1.60 cubic inches (26 cc), the 160FX develops 3.7 horsepower at 9,000 RPM and operates well across a practical range from 1,800 to 10,000 RPM. It arrives with a Type 60F carburetor for accurate throttle control and the E-5010 silencer to reduce noise during flight, preserving a better experience at the field.
Suggested Propeller Choices
To match different flying styles, use smaller aerobatic props such as 15x12 to 16.5x13 for quick response and climb, and larger sport props like 17x10 to 18x12 for efficient cruising and smoother speed control.
